How to tell a foreach loop only to go through the loop for x times?

how can I achieve this correctly:

$array[]['title'] = $secondarray["title"];
$array[]['content'] = $secondarray["content"];

foreach($array as $arr) {
$output.="<div>".$arr['title']."</div><br/>";
}
unset($arr);

Now for example the $array[]['title'] contains 10 entries and $array[]['content'] also 10. But the foreach loop will give 20 div as result since the $array contains 10+10 elements. How can I tell the foreach to take only the amount of elements in $array[]['title'] (since $array[]['content'] is the content that belongs to each title)? So that means go only 10 times through the loop.

PS: Please no answer that I should use "for".

Thanks for your help, phpheini

i suggest putting title and content into a single array, then you can use foreach without counting and title with its content is 'grouped':

$array[] = array ( 'title' => $secondarray['title'], 'content' => $secondarray['content'] );

foreach($array as $arr) {
  echo '<h1>',htmlspecialchars($arr['title']),'</h1>';
  echo '<p>',htmlspecialchars($arr['content']),'</p>';
}

Another method would be to only feed it a partial array:

foreach (array_slice($array, 0, 10) as $row)
{
    ...

maybe

$array[] = array(
  'title' => $secondarray["title"],
  'content' => $secondarray["content"],
);

after it will be no need to limit loop times

Use something like this, but you should really use LIMIT if data comes from database.

$i = 0;
foreach($array as $arr) {
     $i++;
     $output.="<div>".$arr['title']."</div><br/>";
     if ($i == 10) break;
}
